Guitar Open Tuning Reference

This app and the guitar tunings available on it have aided in my songwriting to the point that I use almost exclusively alternate and open tunings. And it's been the most productive and prolific three years of my career.

MOST USEFUL APP as a Guitarist This is the most useful tool for me Learning to play in open e tuning dropped down 2 steps has been so hard until i found this app A rare find with NO annoying adds, only useful information. Jean-Philippe you Sir, are a true gentleman and a scholar.

Great app for exploring open tunings. Exactly what I was looking for and it is free. Thanks for developing it, Jean-Philippe.
